The Federal Energy Regulatory Commission has authorized Tennessee Gas Pipeline Co. to abandon capacity it leased on Dominion Transmission Inc.‘s system between Ellisburg and Leidy, PA, and granted Dominion authorization to reacquire the capacity [CP13-545-000]. FERC first authorized Tennessee to lease up to 150,000 Dth/d on the Dominion system in 2002. The lease agreement was designed, in part, to facilitate the movement of gas from upstream supply points at Niagara and Dracut, MA, and from the Gulf Coast to new markets at Leidy, which is in the heart of Pennsylvania’s Marcellus Shale. FERC made the abandonment authorization retroactive to Sept. 30, 2013, as had been called for in both the original lease agreement and the application for authorization to abandon capacity, both of which were filed jointly by Dominion and Tennessee. The companies said no customer would lose service by Tennessee’s abandonment of the leased capacity.
